Google Cloud Dedicated Interconnect
High-availability, low-latency connection
Dedicated Interconnect provides direct physical connections between your on-premises network and Google’s network. Dedicated Interconnect enables you to transfer large amounts of data between networks, which can be more cost-effective than purchasing additional bandwidth over the public internet.

How does Dedicated Interconnect work?
Connect between the Google network and your own network
For Dedicated Interconnect, you provision a Dedicated Interconnect connection between the Google network and your own network. The following example diagram shows a single Dedicated Interconnect connection between a Virtual Private Cloud (VPC) network and your on-premises network.
For the basic setup shown in the diagram, a Dedicated Interconnect connection is provisioned between the Google network and the on-premises router in a common colocation facility. Your setup might be different if your on-premises router is not in the same colocation facility as your Dedicated Interconnect demarcation.
When you create a VLAN attachment, you associate it with a Cloud Router. This Cloud Router creates a BGP session for the VLAN attachment and its corresponding on-premises peer router. The Cloud Router receives the routes that your on-premises router advertises. These routes are added as custom dynamic routes in your VPC network. The Cloud Router also advertises routes for Google Cloud resources to the on-premises peer router.

Provisioning
To create and configure a Dedicated Interconnect connection, you start by deciding where you want a Dedicated Interconnect connection and whether you want MACsec for Cloud Interconnect. Then, you order a Dedicated Interconnect connection so that Google can allocate the necessary resources and send you a Letter of Authorization and Connecting Facility Assignment (LOA-CFA). After you receive the LOA-CFA, you need to submit it to your vendor so that they can provision the connections between Google’s network and your network.
You then need to configure and test the connections with Google before you can use them. After they’re ready, you can create VLAN attachments to allocate a VLAN on the connection.
For detailed steps to provision a Dedicated Interconnect connection, see the Provisioning overview.
